A friend of mine sent me the following screen-shot today (note the row underneath the ad in premium position):

I instantly ran a search for “pscore mcpc thresh” and found zero results, which made me think those must have been internal variables leaking out of AdWords in debug mode.

Then a colleague pointed me to WebmasterWorld, where a user had posted a similar screen-shot in the Google AdWords forum.

Now, what do those variable names (and values) mean exactly?

Here’s my guess:

Pscore

The component of Google’s Quality Score influencing ad position.

mCPC

The keyword’s minimum CPC bid.

thresh

A threshold of some kind: maybe a minimum Pscore?

What do you think?
